word生成及word转pdf

生成word文档

1. word模板转xml ，字符串替换。复杂不可维护。（不推荐）
2. Poi-tl 。Word模板引擎，基于Apache POI，提供更友好的API，低代码，准备文档模板和数据即可。（推荐）

着重poi-tl

Poi-tl

引入依赖

       
            org.apache.poi
            poi-ooxml
            4.1.2
        
      
            com.deepoove
            poi-tl
            1.9.1
